Too Much Salt Hurting Majority of Americans

March 26, 2009 -- Americans already eat way more than the recommended amount of salt, and now the CDC finds that even lower recommendations apply to 70% of us.

New data show that the average U.S. adult consumes one-and-a-half teaspoons of salt every day. That's a half teaspoon more than the basic daily recommendation of one teaspoon (about 2,300 milligrams of sodium).

But the recommendation is much lower for people with high blood pressure, people over 40, and all African-American adults. These groups should be eating no more than two-thirds of a teaspoon of salt (about 1,500 milligrams of sodium) per day.

More than two out of three Americans -- some 145.5 million of us -- are in those categories, the CDC now calculates.

Seven out of 10 U.S. adults get 2.3 times the healthy amount of salt. It's putting us in a world of hurt, says Darwin Labarthe, MD, PhD, director of the CDC's division for heart disease and stroke prevention.

"This is a very important message," Labarthe tells WebMD. "There is no room for debate any longer that a high level of salt causes stroke and heart disease, and that lowering salt intake will diminish these very serious health consequences."
